DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the drawings.

FIG. 1 shows the structure of a photographing apparatus to which the present invention is applied. First, the configuration of the entire apparatus will be described along the flow of the photosensitive material that is subjected to the photographing process.

In FIG. 1, reference numeral 1 is a supply magazine for storing a sheet film such as an X-ray film, and the film 2 stored in the supply magazine 1 is an upper layer portion by a suction plate 5 attached to an interlocking mechanism 3a. One sheet of film is adsorbed and taken out.

The interlocking mechanism 3a is configured as described below,
By the motor 3 so that the suction plate 5 separates only the first film 2, the vertical movement for taking out the film from the supply magazine and the forward and backward movement when the taken-out film is conveyed to the conveying path are performed. Driven.

The film 2 adsorbed by the adsorption disk 5 is sent to a roller 6 driven by a motor 7 and is guided by a guide 1.
It is conveyed along the line 1 and fed to the roller 9.

Roller group 12 in the process after roller 9,
Pulse motors 15 and 17 are intermittently driven.

When the trailing edge of the film 2 entering from the roller 6 to the roller 9 reaches the position of the photo sensor 10,
By stopping the drive of the motor 18 by the detection signal of the photo sensor 10, the rotation of the roller 9 is stopped and the film is once stopped.

Next, the motor 8 is driven to drive the cam mechanism 8a.
The film guide plate 11 whose front end is bent as shown in the figure moves to the position of the broken line, and guides the film 2 so that it is fed from the rear end toward the roller 12.

After that, the motor 9 reverses the roller 9 to feed the film 2 toward the roller 12. As a result, the leading edge of the film 2 is guided by the guide plate 11 (at the position of the broken line).
Is guided to the roller 12 and further stops when the leading edge of the film 2 reaches the photo sensor 13, and with this position as a reference point, the pulse motor 18 is pulse-driven by the CPU incorporated in the control circuit and stored in advance. The film 2 is moved to the predetermined exposure position by driving the rollers 12 to 15, and the TV monitor 25
Take an image of.

Filming in the direction of travel of the film 2 is performed by moving the film 2 as described above, but shooting in a direction other than the direction of film travel, that is, in the vertical direction in the drawing, is T.
The V monitor 25 is moved by the drive device 19 in a direction perpendicular to the plane of the drawing.

That is, a plurality of images arranged in rows and columns can be obtained by a combination of movement of the TV monitor 25 in the vertical direction of the drawing (row direction) and movement of the film 2 (column direction).

When the predetermined photographing is completed, the rollers 15 and 1
Films 2 and 9 are reversed and the film 2 is returned to the roller 9,
When the trailing edge of the film reaches the photo sensor 10, the pulse motor 18 is stopped and the guide plate 11 is returned to the solid line position by the motor 8.

Next, the pulse motor 18 starts reversing,
The roller 9 moves the film 2 in the upper direction of the figure.
The film 2 is guided by the guide plate 21 and conveyed to the roller 17, and is stored in the receive magazine 23 to complete the photographing.

The photographing plane box 26 provided on the photographing plane
Is to maintain the flatness of the film by sucking air by a vacuum pump (not shown) to suck the film 2.

Next, the structure of the interlocking mechanism 3c for taking out the film from the supply magazine 1 will be described (for details of the mechanism, see FIG. 2 and subsequent figures).

The crank pin 33 at the tip of the crank 3c attached to the rotary shaft of the motor 3 is engaged with the cam plate 34 attached to the swing base 35, and is rotated by the rotation of the motor 3 (in the direction of the arrow). The swing base 35 is swung upward.

The rotational position of the crank of the motor 3 is detected by photosensors 36, 37 and 38. The photosensors 36, 37, 38 are shielded by a sector metal fitting 39 provided on the crank of the motor 3, and the crank rotation angle of the motor 3, that is, the swing base 35, depends on which sensor detects the sector metal fitting 39. The oscillating position and the attitude of the lever 45 are feedback-controlled.

An arm 40 is provided at the left end of the swing base 35 (on the insertion opening side of the supply magazine 1) in the lateral direction of the supply magazine 1 (direction perpendicular to the plane of FIG. 1). Reference numeral 40 rotatably supports the swing base 35 via a shaft 41 arranged at a height near the bottom surface of the supply magazine 1. A suction plate base 46, to which a plurality of suction plates are attached, is rotatably attached by a support shaft 42 to the end of the swing base 35 on the opposite side of the arm 40 (that is, the direction toward the back of the magazine entrance).

The suction board base 46 is urged clockwise by a spring 43 and is stopped at a predetermined position under the control of a stopper 44. Further, a suction plate rotation lever 45 is rotatably attached via a support shaft 50 between the cam plate 34 of the swing base 35 and the suction plate 5, and is biased clockwise by a spring 47. It is stopped in place.

Part of the lever 45 (outside the magazine entrance)
Is arranged so as to engage with the crank pin 33 of the motor 3, is pushed downward by the rotation of the motor 3, the lever 45 is rotated counterclockwise, and the other end of the lever 45 (magazine) is rotated. The inside (from the entrance) is attached so as to engage with the suction board base 46 and rotate the suction board 5 counterclockwise.

Next, the outline of the operation of the above-mentioned take-out mechanism will be described with reference to FIGS. 2, 3, and 4. FIG. 2 is an enlarged view of the structure of the take-out mechanism portion of FIG.
Shows the state where it has dropped down onto the film in the supply magazine 1. FIG. 3 shows a state in which the film is adsorbed and lifted up, and FIG. 4 shows a state in which the lifted film is carried to the roller 6.

Half of the upper surface of the supply magazine 1 is an opening 1a which is opened and closed by a shutter (not shown),
The swing base 35 is driven by the motor 3 through the opening 1a.
The suction plate 5 supported by the above is lowered onto the uppermost film 2 in the supply magazine 1, and the suction plate 5 is sucked by a suction mechanism (not shown).
A negative pressure is applied to and the end area of the film 2 is lifted as shown in FIG.

In the above operation, since the support shaft 41 of the swing base 35 is provided in the vicinity of the bottom surface of the supply magazine 1, the leading end of the film 2 is lifted while drawing a locus indicated by the symbol H in FIG. Touch the side wall and the lid,
No scratches and film 2 due to its resistance
It is possible to prevent the paper from falling or inducing a jam by dropping to a position other than the proper position.

In FIG. 3, the swing base 35 is at the most raised position, but this position is the photo sensor 3
Feedback control is performed by detection by 7.

Thereafter, as shown in FIG. 4, the motor 3 rotates to the sensor 38, and the crank pin 3 of the motor 3 is rotated.
3 pushes down one end of the lever 45 to rotate the lever 45 counterclockwise, and the other end of the lever 45 pushes the suction plate base 46 to rotate the suction plate counterclockwise about the shaft 42 as a pivot. The tip of the adsorbed film is gripped by the roller 6. At the same time, the negative pressure of the suction plate 5 is released, the film is separated from the suction plate, and the film is conveyed by the roller 6.

When the motor 3 moves from the sensor 37 to the sensor 38, the cam 34 and the crank pin 33 have a cam shape of the cam plate 34 so that the swing base 35 is always located at the uppermost position during this period (see FIG. 4). The shaded area P) is set.

The sensor 36 controls the position where the swing base 35 is most lowered, and is set to a position where the film can be lowered to the position height of 0 in the supply magazine with a margin. There is.

According to the above embodiment, one motor 3
The crank 3c provided on the above is engaged with the cam plate 34 of the swing base 35, and the swing base 35 and the suction plate 5 are swung in the vertical direction by the rotation of the motor. It is taken out and moved to the height of the roller 6.

Further, by the same rotation of the motor 3, the suction plate 5 is moved in the front-back direction through the engagement of the crank 3c and the lever 45, and the film 2 is transferred to the roller 6. In this drive process, the shape of the cam plate 34 is determined so that the swing base 35, and thus the vertical swing position of the suction plate 5, does not change.

That is, according to the above-mentioned embodiment, one drive motor, the crank mounted on the motor shaft, the vertical driving cams engaged with the crank,
The suction plate 5 can be swingably driven in two directions only by a simple mechanism including a lever for driving in the front-back direction, and the film 2 is taken out from the supply magazine 1 and delivered to the roller 6 at the entrance of the transport path. Can be done reliably.
Therefore, it is possible to significantly reduce the size of the device and reduce the cost.

In the above, the swinging of the suction plate 5 in the vertical direction,
Although the rocking in the front-rear direction is performed almost continuously, it is needless to say that these may be performed at substantially the same time or at a partially overlapping timing by setting the cam shape or the like.
